Welding Of Aluminium Alloys. Alloy 4043 has a 5 silicon Si content while. However with stronger alloys such as 5083 5183 or 5556 filler metals should be used.
Alloys A6016 6056 and 6061 -T6 to a low carbon steel DC. 7020 series can be fusion welded with arc-based processes. When welding aluminum each alloy must be used with the proper welding wire.
US7939182 FILLER WIRE FOR WELDING ALUMINUM ALLOYS Aluminium Pechiney France An aluminum-based welding filler wire is made with an aluminum alloy that contains between 01 and 6 wt.
In general the non-heat-treatable aluminum alloys can be welded with a filler alloy of the same basic composition as the base alloy. Arc welding is commonly used for joining aluminium alloys. It provides a basic understanding of the metallurgical principles involved showing how alloys achieve their strength and how the process of welding can affect these properties. There are numerous processes that can be used for welding aluminium and its alloys which are detailed below.
